Application filed April 7, 1916. I Serial No. 89,652.

To all whom it may concern:

Be it known that I, EUGENE A. KUEN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and use ful Improvements in Lamps, of which the following is a specification.

My invention relates to lamps of the character of those known as headlights for use,

.for instance, on automobiles, and comprising a body, a reflector and a closure. It is the object of my invention to provide simple means for assembling theparts and maintaining the parts in assembled relation. I

The invention will be readily understood from'the following description and claims,

. and from the drawings, in which letter:

Figure 1 represents a perspective viewof the lamp parts in separated relation.

Fig. 2 is a detail in front elevation of the body and reflector in relation about to be connected.

Fig. 11 is a similar view showing body and closure assembled.

Fig. 12 is a longitudinal section taken on the line- 12-12 of Fig. 5, showing the re-. flector about to. be assembled in the body.

. Fig. 13 is a similar view showing the reflector assembled in the body and the closure about to be assembled on the body.

Fig. 1.4 is a similar view showing he parts in assembled relation; and,

Fig. 15 is a detail showing the manner of connecting together the ends of the annularly arranged spring.

21 represents the body of the lamp. 253 represents the reflector and 23 the closure.

The reflector is of generai parabolic form the and adjacent to its outer edge is provided with a rearwardly extending annular bead 24 forming an annular groove 25 in which an annular cushion-member 26 is secured in suitable manner, as by being cemented therein. This cushion-member may be a cord, or of fabric, rubber or other suitable material. At the outer edge of the annular bead 24 there is a rearwardly projecting annular wall 27 which merges into a laterallyextending annular flange 28 with an annular rounding 29.

The body is shown of general parabolic form and adjacent to its front end is pro vided with an annular bead 31, forming an inner annular groove 32, from which a cylindrical portion 33 of the body projects forwardly. Bulges 34 are formed in this cylindrical portion and project outwardly to sub stantially the diameter of the annular bead 31.

The closure or door comprises a ringmember 86 and a lens member 37, the latter preferably of glass. The ring-member has a rearwardly extending cylindrical portion 38 and an inwardly extending portion 39, the lens member being received across the latter and preferably held to the ring-member by means of clips 40 extending over the edge of the lens member and secured in suitable manner,- as by soldering or brazing to the ring-member.

The forward end of the body is provided with slots 43, of which a suitable number are disposed about said forward end. The slots respectively have forwardly inclined walls 44., which at their rear ends merge into notches 45. Inwardly extending recesses 47 are formed in the forward end of the body and merge with the slots 43. These recesses preferably extend rearwardly from the for- The wall at one side of the respective recesses is cutaway, as shown at 48, for forming the beginning of the slot 43, the other side of the wall of the recess extending downwardly and forming an inwardly extending lip 49 arranged to be received over the peripheral edge 50 of the reflector. The slots 43 are provided with clearance enlargements 51 at their ontrance ends.

The edge of the reflector is provided with a suitable number of notches 52 arranged to be received about the inwardly extending walls of the recesses 47.

The ring-member 313 is profiled Wliliii suitable number of inwardly extending pins 55 which are arranged to be received through the recesses 47 and into the slots 43 and, by rotation of the closure, are arranged to pass lengthwise of the inclined walls 44, whereby the closure and body are drawn toward each other, and to be received in the notches 45 for maintaining the parts in locked relation. The pins are respectively rigidly secured to the ring-member as by having the pin pass through a hole 56 in the cylindrical portion 38, the cylindrical portion being clamped between the head 57 of the pin and a shoulder 58 struck up thereon.

An annularly arranged wire spring-ring 61 is provided having spring-lips 62 bent integrally therefrom, the ends of the wire being connected by bending said ends inwardly toward the center of the ring, as shown at 63, then outwardly and crossingly, as shown at 64, and then inwardly and about the opposite end of the wire for forming an encircling knot 65 and rigidly connecting said ends. The annularly arranged spring-wire is resiliently received in the an nular groove 32 of the body, the resilient dips 62 projecting radially slantingly inward and toward the open end of the body and held in normal position by contact with the annular'shoulder 66 between .the annular bead 31 and cylindrical portion 33 of the body. The 'inner ends of the resilient lips are provided with an inward bond 67 for causing easy riding of the reflector parts upon the lips in assembling the parts and preventing obstructing contact of the ends of said lips with the head 24.

The manner of connecting the ends of the wire spring-ring insures that the slant of all the lips 62 shall be equal and exert equal pressure upon the reflector at their various points of contact with the reflector,

for the reason that torsional twist in thewire is resisted at both end" of the wire by the laterally extending encircling knots 65 encircling the laterally extending bends 63 and having reversely laterally extending stretches 64 between said knots.

A suitable light element, for instance, an incandescent electric light-bulb 71 is suitably secured in the reflector by means of a suitable socket T2,suitably secured in the re-- flector or body, and suitable means are provided, if desired, for adjusting the socket with relation to the reflector and the lightbulb in the focal axis of the reflector. not shown because well known.

In assembling the parts, the reflector is received in the body of the lamp, with the inner edge of its annular flange 28 resting on the resilient lips 62, as indicated in Fig. 12, the notches 52 registering with the walls of the recesses 45, as indicated in Figs. 2 and 6. Pressure being applied upon the in the recesses 47, as indicated in Figs. 4.

and 8. Upon pressure being brought to bear upon the closure toward the body and rotative movement being applied to the closure, the pins will be caused to be received in the'slots 43 and to ride upon the inclined walls 44 for drawing the closure and body toward one another in a direction parallel to the line of the principal axis of the re-- flector. Contact will thereby be made between the closure, preferably by its transparent member 37, with the annular cushion member 26, and pressure applied to said pushion-member, the pressure upon the reflector by means of the closure being exerted through the annular cushion-member, the reflector also being moved inwardly, resisted by the action of the resilient lips 62, placing the parts in the relations shown in Figs. 9, 11 and 14.

The outwardly extending bulges 34- insure central location between the closure and the body and also provide ready rotative movement and reduce friction -during said movement. I

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a lamp, the combination of a body, a
